Abstract

Using the approximation of a polydisperse ensemble (nonreflecting, two-layer, and
homogeneous spheres), a theoretical analysis is presented of how the internal structure
(as a result of variation of the moisture in the air) affects the absorption coefficient
and single-scattering albedo of an ensemble of small hygroscopic, inhomogeneous, and
absorbing particles of the sulfate component of the marine aerosol in the boundary layer
of the atmosphere. The variations of these optical characteristics of the aerosols in
the IR, visible, and UV regions caused by variations of the microstructural parameters
of the aerosol particles are studied. It is shown that neglecting the radial
inhomogeneity of the structure of the aerosol particles can result in large errors when
estimating the absorption coefficient and consequently can cause large errors when
calculating the radiational and thermal regimes of the boundary layer of the
atmosphere.
